I assume you are changing the outdoor unit to a 2 compressor setup where you will be running at approx. 50% capacity most of the time. I would get the information off the valve and check it out with the manufacturers specs. to see if it will control under reduced volume conditions. If its an OEM valve with no info, you may want to research the Sporlan web site. Its a pain to change a TXV but not as much a pain as callbacks.

No! Some people bought a ahu to replace their leaking coil one. Thier old unit is a r-22 single circuit. They were told that no more R-22 AHU 7.5 ton can be found so they bought this dual circuit 410A AHU. I know i can change it over to r-22 but how about the dual circuit?
